Superior Performance The 312D hydraulic system increases efficiency and performance by increasing hydraulic pressure by 2% to improve lift and digging forces. Auxiliary hydraulic lines and wires are routed on the boom base, making the hydraulic circuit easier to install. This compact design reduces line length, reduces friction and pressure drop, and increases the efficiency of power usage.
Hydraulic shock absorbers at the rod end of the boom cylinder and both ends of the stick cylinder dampen vibration, reduce noise and extend cylinder life. When controls are inactive, flow is minimized to reduce fuel consumption and extend component life. Electronic underspeed control uses electronic technology to regulate pump output so that it does not exceed engine power, eliminating the need to store engine power to avoid engine stall. The hydraulic cross-sensing system utilizes two hydraulic pumps to fully power the engine under all operating conditions, allowing faster and stronger pivot rotation as implement speeds increase, increasing productivity.
